[MON] Monitor Squelch Noise Press the MON button to start or stop monitoring squelch noise. This allows you to set a comfortable volume level. [SCN] Channel Scan Press the SCN button to start or stop scanning channels in the scan list. Channel Scan operation occurs only during receive operation. To add or delete the current channel from the scan list, press the SCN button and hold it down for 1 second or more. See "Channel Scan" on page 10.
[ TA ] Repeater Talk Around Press the TA button to turn Repeater Talk Around on or off.

This function may be used on any channel that is programmed to a frequency pair (repeater channel). [NXT] Next Scan List Channel Press the NXT button to select the next consecutive channel in the scan list (not during scan operation).
BUILT-IN FEATURES Bendix/King EMH radios are based on a microprocessor core that allows extra features and operational characteristics to be built into the radio. Your dealer will help define the best operational settings for your system and program them into the radio. ADDITIONAL FREQUENCIES Additional transmit and receive frequencies can be added. If you wish to monitor other local radio systems that fall anywhere in your band, a frequency with or without Code Guard can be added to your program.
KEYPAD MICROPHONE OPERATION If a keypad microphone is used with the EMH radio, the following features may be enabled. Not all microphones support these functions. Contact your dealer to determine which features are available with your microphone and have been enabled in the radio. GROUP SELECTION Select a channel group by pressing the # key on the keypad microphone followed by the number of the desired group. This is used only if the radio has been programmed to divide the available channels into groups.
USER SELECT PRIORITY CHANNEL Press the PRI button on the keypad microphone to make the current channel the fixed priority channel. The PR annunciator appears on the display. This occurs in priority scan modes B, C, and D, but not A. See "Priority Scan" on page 11. USER SELECTED CODE GUARD When the frequencies are programmed for each channel in the radio, a receive Code Guard value and a transmit Code Guard value may also be entered for each channel.
CHANNELSCAN Press the SCN button to start or stop scanning channels in the scan list. Scan operation occurs only while the radio is not transmitting. Scan operation is indicated on the display by the flashing SCN annunciator (alphanumeric mode) or two flashing bars (numeric mode). The radio scans all channels in the scan list for activity. When activity is detected, the radio receives the active channel, and the channel name or number appears on the display. Channels in the scan list are pre-programmed.
Press the PRI button to start or stop priority scanning. Priority scan operation occurs only during receive operation. Priority scan operation is indicated on the display by the PR annunciator and either the flashing SCN annunciator (alphanumeric mode) or two flashing bars (numeric mode). To make the current channel the fixed priority channel, press the PRI button and hold it for 1 second or more. A beep sounds and the PR annunciator appears when the priority channel change is executed.
PRIORITY MODE B In priority mode B the priority mode is fixed in programming and indicated by the PR annunciator when the priority channel is selected. Priority operation during scanning is the same as with Priority mode A, except that the priority channel is pre-programmed, not the selected channel. However, with any channel selected other than the fixed priority channel with SCN off and PRI on, the receiver checks the priority channel while receiving on the selected channel.
BUSY CHANNEL If your radio has been programmed by your dealer for busy channel operation, it will operate in one of the following three modes. BUSY CHANNEL INDICATION The yellow Busy Channel Indicator glows if there is carrier activity on the channel selected. If the channel selected is a Code Guard channel and the correct code is not detected, the Busy Channel Indicator remains on for the duration of the carrier activity and no messages are heard.
INSTALLATION Plan your installation carefully. Locate the radio and microphone within easy reach, giving the operator a clear view the display. Do not locate the radio or microphone in a position that interferes with safe operation of the vehicle. Once the equipment location is chosen, determine the best routing for cables and wires to connect the system. Use a rubber grommet to protect the wires when passing through sheet metal.
SERVICE If you need service, contact your Bendix/King dealer or any other Bendix/King dealer equipped to service your radio.
